In the southern part of Georgia, we have two species called garfish. The 

 largest inhabits the salt-water rivers and Atlantic ocean, and the other our swamps 

 and fresh-water canals of the rice-fields. The head and jaws of the former are 

 much longer and more slender than those of the latter. 



The viscera of the fresh-water species are represented in Fig. 11. 



The blood coagulated in an imperfect manner, and, in the course of an hour, the 

 fibrin dissolved and the blood-corpuscles settled to the bottom of the vessel, leaving 

 the clear serum above. In one of the vessels, the blood scarcely coagulated, and 

 the fibrin dissolved in twenty minutes. 



It is characteristic of the blood of Fishes, that the arrangement of the atoms of 

 albumen, so as to form fibrin, is very unstable. This instability and imperfection 

 of the fibrin is indicative of a feeble state of the vital force, and, as a necessary 

 consequence, of an imperfect condition of the organs which elaborate the blood.

4. Eana catesboeana, Shaw. Bullfrog. July 30. 



The stomach of this Batrachian contained several Crawfish (Astacus Bartoni), and 

 a long slender Grass Snake [Tropklonotus ordinatus) about three feet in length. It

 have settled its precise synonymy.
